Error Message:

The Microsoft cluster server could not write file (filename ). The disk may be low on diskpace, or some other serious condition exists.

Explanation:

The cluster service attempted to create a temporary file in the \Mscs directory on the quorum disk. Lack of disk space or other factors prevented successful completion of the operation.

User Action:

Check the quorum drive for available disk space. The file system might be corrupted, or the device might be failing. Check file-system permissions to ensure the cluster service account has full access to the drive and directory.
